[Linux-gpib-general] libgpib: error locking board mutex with NI PCI-GPIB

[Averty, B. <bru...@ed...>]

Hi,

got installed in april the gpiblib 3.1.92 with the National Instruments
PCI-GPIB card, works great !!! (good job, total respect)

I have download the  3.1.97 last week, and boom !! error : "libgpib: error
locking board mutex!"

I have the same error what ever I use (my own programs, ibtest, ...)

any ideas ?
